Aging is associated with a decline in hormones and an associated decline in GABAergic function and calcium and ion current dysregulation. Neurosteroid hormones act as direct calcium channel blockers, or they can act indirectly on calcium channels through their interaction with GABA receptors.
Hormone replacement therapy and various devices exist to treat signs of aging, such as skin thinning, yet there are no reviews summarizing or evaluating their role in neocollagenesis and the associated increase in skin thickness.
The hair cycle and hair follicle structure are highly affected by various hormones. Androgens-such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)-are the key factors in terminal hair growth.
Dehydroepiandrosterone (DHEA) is a steroidal hormone secreted by Zonareticularis of the adrenal cortex with a characteristic age related pattern of secretion. These hormones are inactive precursors that are transformed into active sex steroids in peripheral target tissues. These hormones are used for the energy, vitality and the natural support of most bodily functions that involve the endocrine system.
Westernized diet and nutritional metabolism are important in acne pathogenesis, especially in adult patients. However, clinical and basic data are lacking. Pattern identification (PI) is a tool that results in a diagnostic conclusion based on a cluster of concurrent symptoms and signs in traditional medicine. Acne can be classified by PI.
Dehydroepiandrosterone (DHEA) has attracted considerable attention as a means against the decrements of aging. This review will summarize clinical studies evaluating DHEA as a treatment option for age-related conditions and diseases.
Dehydroepiandrosterone (DHEA) and its sulfate conjugate (DHEA-S) are the most abundantly produced human adrenal steroids to be reduced with age. DHEA may be related to the process of skin aging through the regulation and degradation of extracelluar matrix protein.
